PATCH: userscripts/Sounds.sh: for Non-FHS systems, use the runtime dir

on Non-FHS systems like NixOS, the system sounds are located
in /run/current-system/sw/share/sounds according to XDG specification
This patch allows the script to fallback to this directory if the
sound files are not found in /usr/share/sounds or $HOME/.local/share/sounds
